[matteoworld]

Buona sera,
sto cercando ci configurare un Cisco 2851 con interfacce Seriali (collegate a FastFrame Telecom SHDSL 2MB)

interface GigabitEthernet0/0
ip address 3.#.#.21 255.255.255.252

interface GigabitEthernet0/1
ip address 2.#.#.17 255.255.255.252

ip route 0.0.0.0 0.0.0.0 Serial0/2/0.1

In questo modo con G0/0 navigo settando il pc con 3.#.#.22

Cambiando
ip route 0.0.0.0 0.0.0.0 Serial0/2/0.1
!
con
ip route 0.0.0.0 0.0.0.0 Serial0/2/1.1
!
In questo modo con G0/1 navigo Settando il PC con 2.#.#.18


Esiste un modo per far Navigare le due LAN in contemporanea con due PC differenti?
Non mi interessa fare bilanciamento di linea semplicemente
PC1->ip pubblico 22 su Linea 1
PC2->ip pubblico 18 su Linea 2

Tutto questo per non utilizzare due Router... visto che ho la HWIC con due seriali e 2 porte GiGabit..
Attendo Vostre solution..

ip route 0.0.0.0 0.0.0.0 96.y.y.y track 3

Also you could add IP SLA to monitor those links. In case of failure one of the links it will be removed from routing table.

ip sla 1

icmp-echo 4.4.4.4 source-interface FastEthernet0/0
